Mugen Shinshi: Bouken Katsugeki-hen OVA

Great scene from a 1987 anime, posted by http://trifecta3.net/.
A club dancer named Atsuko Fukune is kidnapped by some strange group. She is sedated (with an injection) along with some other girls and brought aboard an airship. They go to a pyramid-like temple.
The bad guys dress Atsuko up in a bikini outfit and stuff her in a cage, where she is part of some ritual. She is tape gagged along with other girls!
